Wilbur the Gay Unicorn, the second book in The World of Ralph Pincus series, will be available in November.

I haven't set a firm date yet because I'm trying to generate interest in my work by building up a subscriber base for my mailing list. The first book in the series, Ralph Pincus, Occultist Extraordinaire, will be free for a limited time to help out with that.

UPDATE (January 5, 2016): I set a firm date. It was November 19th. The ebook version of Ralph Pincus, Occultist Extraordinaire is still free at Amazon, Barnes and Noble, Smashwords, iTunes, Kobo, and Noisetrade.
